Blender to Kerkythea problem

Sure the solution is already in the forum, but I didn't found it...

Exporting the Camera Path with the Blender2KT version works well...
But: Speed of camera animation from the IPO-Curve wont work, right?

Then I tryed to export as animation as kst-file. I get the error message "oject camera.target not found"...
What to do??

Thanks for your help...

no blender users with an answer here?!

Ok, I explain better:

Kerkythea works great for me, only the camera animation I would like to do in Blender! So I need to have the camera exported, also with speed variations ecc. As I already have my materials in K and in Blender its limited, I would like to assign these in K, also the GI globals like physical sky ...
So I need to export the camera to merge in kerkythea or have a script that works...don`t even know if this is possible...in future maybe I would need also object animation...
I also tried the kst export script, but it comes out a python error message (see my post on thread "KST-Animation Export V 1.0")
Until now I use the script export "kerkythea camera animation" to export an xml to merge with the existing scene...but this is without speed variation of camera movement

Anybody has an idea?
